Metrics question
You suspect data quality issues are being introduced at multiple points in the human-data pipeline, but the team lacks visibility into where drop-offs, disagreements, or rework originate. What observability capabilities would you prioritize first, and how would you decide whether that investment should come before new labeling features?

What this question tests
Tests prioritization of observability investment against feature work in a pipeline with unclear points of data quality failure.
How to approach it
- Map pipeline stages where quality could degrade, for example task instructions, annotator judgment, reviewer disagreement, and post hoc rework.
- Identify the cheapest instrumentation that localizes the problem fastest, such as logging disagreement rates and rework counts at each stage.
- Prioritize observability that answers where, not just that a problem exists, since the team knows quality is an issue but not its source.
- Compare the cost of continued blind fixes against a focused observability sprint, since shipping features that miss the real cause wastes effort.
- Decide observability comes first whenever the team cannot currently tell which stage to fix.
What a strong answer includes
- Proposes specific, cheap instrumentation first, such as disagreement rate and rework logging per pipeline stage, rather than a vague call for more visibility.
- Frames the decision as an information value problem, arguing that fixing blind is more expensive than a short, focused observability investment.
- Draws a clear line for when observability should come before features, namely when the team cannot currently localize where quality breaks down.
- Proposes a time boxed observability sprint rather than an open ended investment, protecting momentum on the roadmap.
Common mistakes
- Jumping straight to new labeling features without first localizing where in the pipeline quality actually breaks down.
- Treating observability as a permanent, open ended investment instead of a time boxed diagnostic step.
Likely follow-up questions
- What would you instrument first if you could only add one new metric?
- How would you decide observability was done and it was time to move to fixes?

- A design-partner customer says adoption of Claude Tag on a newly launched surface spiked at launch and then stalled. How would you diagnose the problem, what metrics and segmentation would you examine, and how would you determine whether the root cause is onboarding, permissions friction, model behavior, or weak product-market fit for that surface?Anthropic · Metrics · Hard
- Assume many new Claude users sign up but never reach a meaningful first-use moment. How would you diagnose where activation is breaking in the onboarding or first-run experience, what first experiment would you launch, and what guardrail metrics would you use to ensure trust and safety are not harmed?Anthropic · Metrics · Hard
